Le Spectre du professeur Hichcock

Made during the pseudonym craze of the 1960s, the music score was credited to "Franck Wallace." Italian composers usually registered their pseudonyms with their performing right society, the SIAE, and the identities were listed by Bianco e Nero and the Monthly Film Bulletin who both reported that Wallace was Franco Mannino. However, some reference sources such as Donald C. Willis in 1972 suggested "Franck Wallace" was a joint pseudonym for Mannino and Roman Vlad (the two composers sometimes collaborated and Wallace is a very rough transliteration of Vlad). Even more confusingly, Beat Records released the soundtrack in 2008 and discovered that the surviving tapes in the Nazionalmusic vaults were attributed to Francesco De Masi. So the CD went out credited to De Masi only. De Masi did not work with either of the other two composers, instead being asked at the behest of the director to do a new score, not liking Mannino's effort; what portions thereof are contained in the film, are unknown, as the director seemingly changed his mind again, as Mannino is credited in the film for the score.
